Rails                  
                                          
                                          
  
                                          
  
                                          
                                          
 Trains  Are  So  Constructed  That  They 
 Have To Follow A Set Path. This  Path Is 
 Called A  "Railway", Which Is  Comprised 
 Of Two  Metal Rails, Hence Its Nickname. 
                                          
 Because  The  Low  Friction Between  The 
 Wheels Of The Train And  The Rail Metal, 
 There Are Limits For  How Acute  A Curve 
 Can Be, And  Even More  So For How  Much 
 The  Ground  Under  The  Rails  Can   Be 
 Sloped. Thus A Railway  Is Often Not Led 
 On  Top Of Hills, Rather Through Them In 
 TunnelS   (If  They   Are   Large),   Or 
            Artificial ChasmS.            
                                          
 There Will  Be Trees On  The Side Of The 
 Rails,  But Not Too  Close, Or They Will 
 Be  Cut Down  By  The  Railway Janitors. 
 There  Will  Be  Plains, And  Bodies  Of 
                  Water.                  
                                          
 Trains  Go  By  Day And By Night.  Along 
      The Way, There Is Information       
 Scattered, Often  Put  On Top  Of Poles, 
 To Be  Interpreted By The Train Drivers. 
 Different  Parts  Of  The  Railway  Have 
         Different Speed Limits.          
                                          
 Sometimes, Trains Have To Stop And  Wait 
 For Something To Happen, Far  Away. This 
 Is  Signaled  By  Red  Or  Green Lights. 
                                          
                                  
                                          
 Many People Follow  The  Rails By  Foot. 
 Often  This  Proves  To Be  The  Shorter 
 Path  Between Two Points.  However  This 
 Is  Frowned  Upon,   And  Very  Impolite 
         Toward The Train Drivers!
